Which isn't to say that advancement in materials and engineering can't overcome those thoughts, but I'm not convinced yet. Schwalbe Marathons have been almost flatless for me (one in 3 years). I would love to see how square that thing was after 30000km.

We've got a review of them coming up on BNA. They're under test now (not by me), so we'll get back to you with the ultimate opinion on them. I'm keen to see how they go. At the very least, they'll work well on the kid's bikes.

Hi BFV,

Any idea when the review will be available?

I'm considering these for my commuter bike as fixing flats at night in the rain is not much fun. The adverse comments I've come across so far are that they are a bit slippy in the wet and that whilst they smooth minor bumps, bigger bumps are more harsh which creates a risk of rim damage.

Cheers

It would not be at all strange if history came to the conclusion that the perfection of the bicycle was the greatest achievement of the nineteenth century.

Not sure, Hamster. When we do a review of something, we actually spend time living with the product so that we can give you a good idea of how they work and how they work over time. I'll look into it, though.

So I've been keen to hit the road on these (23mm tyres) however the wheelset they were on has shot bearings. So I waited and waited until I could wait no more, I ripped them off and installed them on a spare A23 rimmed wheelset I had hanging on the wall.Well.... I rode 500 meters and then decided to turn around and change bikes Now, I am confident that my issue with these is that the (23mm) tyres are just two narrow for my A23 rims (maybe 28mm is better suited) and this is the reason for the truly scary squirming sensation I feel as the tyres roll. It was a very unsettling and unstable feeling as they rolled, I only felt confident turning at walking pace - yes that slow. I have been told that they take some time to 'bed' into the rim, however the whole experience just felt way to dangerous to even be on the road that long if they bedded in at all. You're probably thinking I really didn't give it much of a test but I certainly didn't want too. Keen to hear anyone else's first few km's on theses?I'm guessing that the tyres would be fine on a narrower rim - but not the newer trending wider rims that I use.If anyone wants a set of black 23mm H1's that have done 500 meters then let me know...

I sent Dizz a PM with a few questions. His reply is below, but remember that this is only a preliminary opinion.

Hey Hamster,

1. Are they dangerously slippy in the wet...

I dare say if this weather continues you will have that answer this week

2. What's their rolling resistance like, it is claimed by some to be high but I'm only intending to use them for commuting so a little more resistance probably won't be a problem

I have a power meter but it will take some time to determine that (perhaps a month of data). Nevertheless at this stage I'm inclined to feel that it's in the region of -1 or 2%

Hamster wrote:3. Apparently they are more harsh for bigger bumps, potholes etc so is there a risk of rim damage.

Yes, definitely firmer but to be fair I don't ride through potholes. So far, I'm not hearing that "Spoke Ping" that is reminiscent of high tire pressures, low spoke count, bad road surfaces & to much weight but it is early days and there are some ride ahead that will put this to the test.

As a general very early summery I would say privately that; Issue.1 As good as any all weather tyre.Issue.2 Some validity, it may even be as high as -4%.Issue.3 Most valid but I need more K's before I can comment on how much harsher but definitly a firmer ride.

cheers and I hope this helps,Dizz
